A new research paper focused on Schnorr multi-signatures and penned by several notable bitcoin developers has just been released.

Published on Thursday, the paper was penned by developers Gregory Maxwell, Andrew Poelstra, Yannick Seurin and Pieter Wuille. It details how Schnorr multi-signatures can be applied to the bitcoin, and though there’s no guarantee they will ultimately be utilized, this new release could mark an additional step in that direction.

Specifically, the Schnorr concept proposes bundling signatures into one small data entry, rather than having multiple signatures listed individually. This has the result of saving space on the blockchain, enabling it to process more signatures while increasing security, according to the paper.
